I use WordPerfect X13. It has a built-in pdf printer. That is, print to pdf. It also has a built-in pdf to text converter, if you just ask it to insert a pdf document into an open WordPerfect document. I do this frequently with legal descriptions for our reports. Like, deeds come in pdf format, so insert it into a blank document. May need a little clean-up, but sure beats typing it all in by hand from scratch. You can probably buy WordPerfect on Ebay or at Amazon.
Many programs have a save to PDF feature already built-in. If not that, then there is the Microsoft Print to PDF that is built into Windows. If you don't have the latest windows or software that has it built-in then try the free version of Nitro PDF.
